Huge loss of color on images. Please help.

When saving my presentation into a quicktime file, all my images become so dull with loss of color/vibrancy etc. (I save it this way, because I use this file on my IWeb built website) Any ideas on how to correct. Thanks in advance.

Are you using QuickTime Pro? If so, when you open your QT presentation, the Window menu in the toolbar includes "Show A/V Controls", and there you'll find sliders to adjust color, contrast, etc.
Even so, visitors to your website won't necessarily see the same image quality on their screens that you see on yours; so it may be wise to keep your adjustments on the moderate side.

Converting awt to JAI image - please help!

My application needs to be able to create a JAI image and apply dither to it.
I got this working by using the fileload operator in JAI to load the image and convert it to a planar image but when I try to use the awtImage operator to convert the images to planar images it doesn't work.
I really don't understand why this is. The two methods are pratically identical.
This is the method that works and the error diffusion method
public void setDitherOp(String op, String picName,KernelJAI typeDither)
                      //operation name, parameter block
    srcImg = JAI.create("fileload", "Pics/"+picName);
    dataType = srcImg.getSampleModel().getDataType();
              //contains parameters to be used in dither operation
    pb = new ParameterBlock();
    pb.addSource(srcImg);
    layout = new ImageLayout();
    if(op=="ordered")
      orderedDither();
    else if(op=="error")
      errorDiffDither(typeDither);
public void errorDiffDither(KernelJAI typeDither)
      if(srcImg.getNumBands()==1)   //source image has one color band
        LookupTableJAI lut =new LookupTableJAI(new byte[] {(byte)0x00, (byte)0xff});
        pb.add(lut);
        pb.add(typeDither);
        byte[] map = new byte[] {(byte)0x00, (byte)0xff};
        ColorModel cm = new IndexColorModel(1, 2, map, map, map);
        layout.setColorModel(cm);
      else if(srcImg.getNumBands()==3) //source image has three color bands
        pb.add(ColorCube.BYTE_496); //add color cube to parameter block
        pb.add(typeDither);          //add error filter kernel
        System.out.println("error diffusion num bands is: "+srcImg.getNumBands());
      RenderingHints rhints = new RenderingHints(JAI.KEY_IMAGE_LAYOUT, layout);
      ditheredImage = JAI.create("errordiffusion", pb, rhints);
      if(ditheredImage==null)System.out.println("Dithered image is NULL");
This is the one that doesn't!
public void setDitherOp(String op, Image frameImage,KernelJAI typeDither)
    srcImg = JAI.create("AWTImage", frameImage);
    dataType = srcImg.getSampleModel().getDataType();
              //contains parameters to be used in dither operation
    pb = new ParameterBlock();
    pb.addSource(srcImg);
    if(srcImg==null)System.out.println("src image null in set dither op");
    /*if(srcImg!=null)
        ditheredImage = JAI.create("Invert", pb);
    layout = new ImageLayout();
    if(op=="ordered")
      orderedDither();
    else if(op=="error")
      errorDiffDither(typeDither);
public PlanarImage getDitheredImage()
    return ditheredImage;
}The other really odd thing in the method that uses the awtImage operator is this:
if the code to invert the colours is executed it works fine. This must mean that it is creating the planar image from the awt image? I really don't see what the problem could be in that case because it uses the same error diffusion method after that.
Please help me with this - its part of a project thats due up in a few days and I really need to get this part working as soon as possible.

Hi morgair,
Thank you so much for answering!!
You're right - the FileLoad and awtImage operators return different types of objects.
FileLoad returns a RenderedImage
JAI.create("fileload", "Pics/"+picName);awtImage returns a PlanarImage. The sample model and color model are set according to the AWT image data.
srcImg = (PlanarImage)JAI.create("AWTImage", pbAwtOp);Also the error diffusion operation takes a renderedImage as a parameter. It says in the programming guide that the source image and the color map must have the same data type and number of bands. (That would explain why the method using fileLoad worked!)
How do I change the Planar image to a rendered imaage or specify the sample model and colour model of srcImg. I've been trying to do this but am going round in circles - there are descrepancies between the programmers guide and the API and I'm lost..
Any suggestions really really appreciated..

I need to clean up the edges of an image, please help!!

I stained a t-shirt and so to make one that was the same I scanned the image on it in order to later print it on a new t-shirt. I opened the scanned image on photoshop and removed the background, then I used the quick selection tool to select the colors (only has 2 colors) and to recolor it as the colors looked dull. The problem is, the quick selection tool didn't make a 'clean/smooth' selection so the edges are VERY bad and I don't know how to fix this! Please help!!
I took a screenshot of the image I'm working on (so that you can have a better idea) and also a close up on the edges (it's like this in all of the image)

It sounds like you want a vector image.
One word: Illustrator. That's Adobe Illustrator.

Flickering-Image -----Please Help

Pls help meI have one hand image. I am drawing polygon above each finger.
Whenever the user clicks on particular finger, we are changing the color of that polygon.
We are changing the colors of the fingers(polygons) based on the database value when some functionalty is invoked. We are updating this color in PaintComponent of JPanel. The colors are flickering some time.
Please help.
Thanks in Advance.

How to Load External Images - Please Help!

I have created a simple portfolio site. The buttons I created
trigger separate frames. Could I not create a MC (Movie Clip) on
each frame where the images now reside and then when the button is
clicked (On "Click' Goto frame 1) for e.g. then the image would be
loaded from an external folder named "Images" in my website?
I am stumped as to how to set this up. Could someone please
help me?
Thanks

Yes, you can do that. Which version of Flash and which
version of Actionscript are you using?

Lightroom 4 contact sheet print crashes with over 12 images - Please help.

Lightroom 4 consistently crashes every time I attempt to print a contact sheet containing over 12 images. Any less and the task is completed without error, any more and it inevitably crashes. Any thoughts?
My workaround has been to export the images and create large contact sheets in Photoshop CS6, but this takes twice as long.
This is a daily task and is significantly disrupting my workflow. Please help.
Regards,
Eliot

So, I had this problem tonight after experiencing no problems with Lightroom 4 previously. I noticed that in the print dialog box, where you can select to print "all" the pages or a page range, the page range radial was highlighted and the defined page range was "7" to "7". I was only printing one image so I changed the print range to "1" to "1". And it did the trick. Crazy, eh?

Podcast not showing up, neither is image Please Help!

Please help! Any suggestions would be greatly appreciated!

1 22fps sounds odd, perhaps a typo
2 anything over 24 fps is not officially supported at that resolution
3 is your source movie PAL/NTSC/24fps (29.97/25/24 fps) ? It's best not to convert as it can introduce stuttering between different frame rates
4 Even if other parameters are ok, I'm not clear of the bitrate here which should be no more than 5000kbps for h264
5 There was something in the iMovie 08 forum a while back when everyone was annoyed at the dumbing down when videos were looking soft and it was something to do with a deinterlacing flag not being set correctly on exports so only 1 field in a frame was showing making video look soft
6 You are best setting all parameters for output manually as you are largely doing. Winston often recommends using 960x540 at whatever frame rate is needed for HD output as he feels there is little difference in quality
7 Try converting short 20-30 sec clips only until you hit on a formula that works
8 Don't give up - you'll get there, frustrating as it seems

Rating is being applied to EVERYTHING, not just the active image- please help.

Seemingly out of nowhere a particular feature in LR stopped behaving the way it normally does for me.
When I am in the Survey view (in the Library mode) and I have a number of images selected because I am trying to make my selections, it suddenly started applying my star rating to the entire set of say 10 images I have selected, and not just the one that is active. This is very strange- I have never seen it behave like this before. I can't remember hitting anything or changing any settings, but it just seemed to have started out of nowhere.
It appears that if I go in and "manually" click on the star scale that appears below each of the images when you mouse over it, THEN it will apply the star rating to just that one image, but I can no longer just hit the "5" key and have just that one image that's active get the 5 star rating. It's doing it to everything.
I've tried just restarting LR but that didn't change anything. Please please help, as this is really messing up my workflow.
Thank you,
Robyn
I did visit the page below to confirm that it should indeed not be behaving in this manner:

Problems opening images - please help!

I just transferred 350 photos from my camera to my Mac, and the last 179 items I cannot open.
I receive the error message 'Item "Namehere.JPG" is used by Mac OS X and cannot be opened.' These images are also listed as having 0Kb on the disk.
I have found this problem elsewhere on the discussion boards, but it has yet to be solved - does anyone have any ideas?!
These images are very important to me, as they are from a recent trip and my cousin's wedding
Thanks.

I have actually been looking on google for a while trying to figure out how to perminately kill programs when they open, and take them off. it would be a huge help if anyone knows how.

Color Banding issue with FCP and Color...PLEASE HELP!!

Ok so heres whats going on and i'm hoping some can help me out here cause i'm totally lost!
So we have a film shot on HDV. The scenes are mostly dark and well lit. Everything in the FCP timeline looks great (little noisy but great). We brought it over the color and did our color grading and corrections. Once we returned back to FCP, we started seeing some major color banding. We then applied the neatvideo plug-in with helps with noise but it made it far worse.
We are rendering in 10bit but how can we remove this banding!!
Thanks again for the help!

Yeah, you can't critically judge video quality on computer displays. They won't show you an accurate image. Unfortunately, there is no way to send a signal to a video display (HDTV, broadcast monitor) for this purpose from an imac.

HP PRO8500
KEEPS ASKING FOR MAGANTA INK, THEN LOOSE IMAGE, I ALREADY REPLACED INK TWICE BUT ISSUE STILL PERSIST.
PLEASE HELP

Ok, finally got it fixed !
Here's what was causing the issue, and what I did to fix it :
I had free content in my iTunes download queue that I got from the "iTunes 12 days of Christmas" promotion, but the problem was that some of the items (two HD episodes) were too large to fit in my harddrive (I'm running low on free hd space) - so each time I was running iTunes I had to cancel the downloading of those items. On my iPhone, I was able to cancel the downloading once for all, but iTunes somehow wanted to try downloading them even if I deleted them. This was quite frustrating so I sent a mail to the support using the Express Lane feature on the support website, asking for thos items to be removed from my iTunes account - and tadaaaa ! Once a nice guy from Apple deleted them, my iPhone stopped asking for that stupid password !

Adobe CS6 to Lion color-files corrupted, please help...

Long time windows user switched to Apple (had an iPhone and iPad for years, just seemed sensible to buy an MBPR when it was time for a new laptop). That was a few days ago. But now, I'm stumped. Experiencing a slight flicker when browsing and noted some color shift in CS6 - researched online - found an article reviewing the use of the Color Synch Utility. Ran it. Seems to have fixed the flicker, but the Photoshop issue remains. This is the erroir code I am getting:
Checking 92 profiles...
/Library/Application Support/Adobe/Color/Profiles/RedBlueYelllow.icc

/Library/Application Support/Adobe/Color/Profiles/TotalInkPreview.icc
   Tag 'pseq': Required tag is not present.
Verify done - found 4 bad profiles.
I can find no data online about a fix...just other OP's noting the problem. Is there a solution?

Found this answer on Adobe's help site. Thought it might help others. Also hoped somebody might be able to explain how to do what is described here:
http://helpx.adobe.com/x-productkb/global/troubleshoot-icc-profiles-mac-os.html
A system error can occur if the Adobe application accesses a damaged ICC profile. Troubleshoot ICC profiles to determine if they cause the problem:
Move all profiles from the following folders to the desktop:
Library/ColorSync/Profiles folder
Library/Application Support/Adobe/Color/Profiles
System/Library/ColorSync/Profiles
Restart the Adobe application, and try to re-create the problem:
If the problem recurs, move the profiles to their original location.
If the problem doesn't recur, move one profile at a time to its original location and then repeat step 2 until you identify the profile that causes the problem.

Problem with remote rollover of images, please help.

Hello,
I got some great help yeserday on how to set up remote rollovers for a image gallery. It all works great except for when you have the curser in between the thumbnail images at bottom, the 1st image that I placed in large photo spot shows up. Any thoughts on how to fix this? Here is the page so you can look at the code. http://www.test.detarconstruction.com/homes/howard/howard.html
Thank you so very much in advance for all your help
Amy Sue

You have added a "Mouse Exit" action to each of the thumbnails which always replaces the big photo with the startup image 'outside.jpg' each time you leave a thumbnail.
(In source view you can see:
onmouseout="changeImages('big_photo','outside.jpg');return true"
for each of the thumbnails).
If you simply remove all "Mouse Exit" actions the big image that belongs to the last touched thumbnail remains visible even if you leave the thumbnail and until you touch another one.
This may be the effect you were searching for.
